Problems solved by technology

Recently, the wireless communication technology is developed, with the extremely high speed, from a single analog communication system, which only can carry the basic audio and text messages in the early stage, to a digital communication system, which is complicated and can transfer a lot of multimedia messages.
However, different communication standards are used in different areas, so people cannot use the single communication apparatus with the single communication stand

Embodiment Construction

[0021] The invention provides a method and an apparatus of receiving signals and a wireless multimode wideband receiver, which transform an interference signal into an inverse interference signal and combine a wideband signal with the inverse interference signal to get a target signal so as to eliminate the non-linear distortion caused by the interference signal and enhance the efficiency of the wireless multimode wideband receiver.

[0022]FIG. 3 is a flow chart showing a signal receiving method according to a preferred embodiment of the invention. As shown in FIG. 3, this signal receiving method receives a target signal existing in a wideband signal. The wideband signal has a first bandwidth, the target signal has a second bandwidth, and the first bandwidth is greater than the second bandwidth. In addition, the target signal has a center frequency in the wideband signal.

[0023] First, in step 302, the wideband signal is received. Next, in step 304, the wideband signal is down-sample...

Abstract

A method of receiving a target signal existing in a wideband signal. The method includes the steps of receiving the wideband signal, removing the target signal from the wideband signal to obtain an interference signal, transforming the interference signal into an inverse interference signal, and finally combining the wideband signal with the inverse interference signal to get the target signal.

Description

[0001] This application claims the benefit of Taiwan application Serial No. 95119269, filed May 30, 2006, the subject matter of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates in general to a method and an apparatus of receiving signals and a wireless multimode wideband receiver, and more particularly to a high-efficiency method and a high-frequency apparatus of receiving signals and a wireless multimode wideband receiver. [0004] 2. Description of the Related Art [0005] Recently, the wireless communication technology is developed, with the extremely high speed, from a single analog communication system, which only can carry the basic audio and text messages in the early stage, to a digital communication system, which is complicated and can transfer a lot of multimedia messages. In addition, the diversified communication protocols are also created to satisfy the diversified communication requirements...
